Western Christian beat the defending champion and now has a chance to win a title of its own.

The fifth-ranked Wolfpack put together an 8-0 run late in the game to take the lead and toppled No. 1 OA-BCIG 62-54 in the Class 2A semifinals, ending the Falcons' 52-game winning streak.

With the victory, Western Christian moves into the state championship game at 8 p.m., the first appearance in the basketball finals for a school long known for its outstanding volleyball teams.

Brooke Wolterstorff led the way with 16 points and eight rebounds, while Kim Kroeze added 13 points, including three key 3-point baskets in the second half. Alissa Pollema added eight points, five rebounds, three assists and three steals for Western Christian, which has no seniors in its starting lineup and is now 24-3.

OA-BCIG lost for the first time since the semifinals of the 2010 state tournament and finished 26-1. Morgan VanDerSloot led the Falcons with 22 points. Jessie Pauley, who'll play at Northern Iowa next season, added 12 points and nine rebounds.

In a back-and-forth game, OA-BCIG built a six-point lead in the first half, fell behind by four in the third quarter, then rallied to pull ahead. Pauley's two free throws gave the Falcons a 50-49 lead with 3:29 left before some clutch shooting at the line put the Wolfpack ahead to stay.

Pollema went 4-for-4 at the line, Kenzie VandeVegte sank two free throws and Kroeze fed Wolterstorff for a layup, sending Western Christian into a 57-50 lead with 1:43 to play.

Four straight free throws by VanDerSloot cut the lead to 57-54 with 1:13 remaining, but the Wolfpack hit five of eight free throws to wrap it up.

Western Christian finished 23 of 35 at the line and outrebounded OA-BCIG 41-33.
